Module aims
Subject content aims:
- To describe and analyse the physical layer techniques used for current and proposed digital communication systems using twisted-pair cable (such as DSL broadband and gigabit Ethernet), wireless (including WiFi, 4G and broadcast systems), and optical communications, especially fibre-optic broadband
- To analyse the effects of the channel in wired, wireless and optical systems, then describe the techniques used to overcome these, and the standards that have been defined for current and proposed systems
Graduate skills aims:
-
To develop critical skills in the selection, adaptation and application of appropriate numeric and algebraic techniques
Module learning outcomes
Subject content learning outcomes
After successful completion of this module, students will:
- Understand the propagation of signals along lossy transmission lines, including attenuation, dispersion, and cross-talk
- Understand multipath wireless channels, including time dependent fading, dispersion, Doppler spectra and the scattering function, and be able to show appropriate models for these channels
- Understand physical layer techniques for operating over wired and wireless channels including OFDM/DMT and MIMO, giving examples from DSL and Ethernet physical layers for wired systems, and 4G mobile, WiFi and digital broadcasting for wireless
- Have knowledge of the advantages and limitations of optical communications
- Understand the principles and main features of optical sources, detectors and amplifiers
- Understand modulation in optical communications, including direct vs external modulation, the use of eye diagrams and chirp
- Have knowledge of multiplexing: the definition, WDM and TDM and future trends
- Understand limitations in optical links: capacity, sensitivity, physical implementation including dispersion limit, sensitivity/loss limit and dispersion compensation
- Be able to calculate power budgets in amplified and non-amplified links, and understand the main system architectures (grid, ring, and tree)

Module feedback
'Feedback’ at a university level can be understood as any part of the learning process which is designed to guide your progress through your degree programme. We aim to help you reflect on your own learning and help you feel more clear about your progress through clarifying what is expected of you in both formative and summative assessments. A comprehensive guide to feedback and to forms of feedback is available in the Guide to Assessment Standards, Marking and Feedback. This can be found at https://www.york.ac.uk/students/studying/assessment-and-examination/guide-to-assessment/ The Department of Electronic Engineering aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme. In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work. Students are provided with their examination results within 20 working days of the end of any given examination period. The Department will also endeavour to return all coursework feedback within 20 working days of the submission deadline. The Department would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback. The Department will endeavour to keep such delays to a minimum. Please note that any marks released are subject to ratification by the Board of Examiners and Senate. Meetings at the start/end of each term provide you with an opportunity to discuss and reflect with your supervisor on your overall performance to date.
